解决方案：
哎，自己真笨，Google找了半天，都没有找到合适的解决方案，有人说是包依赖版冲突，突然意识到自己主工程里面的pom.xml文件竟然添加了spring-boot-starter-parent依赖<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.0.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent>由于自己是使用
Spring IO进行Spring jar包版本管理，已经做了如下配置，如果再添加上述依赖的话就会造成版本冲突，产生错误。<dependency> <groupId>io.spring.platform</groupId> <artifactId>platform-bom</artifactId> <version>Brussels-SR4</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Dalston.SR2</version> <type>pom</type> <scope>import</scope> </dependency>
注：记下来，吃一堑，长一智
